One year ago, when we first started discussing the Vancouver housing bubble, which as we first speculated - and was later confirmed - was the result of Chinese oligarch money-launderers parking "hot cash" in this offshore housing market (at least until a 15% property tax on foreign purchases made Seattle the new Vancouver), we said that Vancouver houses had become the de facto new Swiss bank account, and because of that the houses - once purchased - would remain a highly overprized, if vacant tribute to China's soaring capital outflows.

Now, courtesy of data by urban planner Andy Yan of Simon Fraser University’s City Program, this has been confirmed because according to the latest census numbers, as of 2016 there were 25,502 unoccupied or empty housing units in the City of Vancouver. Expanding to include the entire metro area, Yan found that vacant or temporarily occupied dwellings have more than doubled since 2001 to 66,719 last year as neighborhoods have hollowed out.

Yan compared census data for Vancouver over several decades to see how the percentage of “unoccupied” units or ones “occupied solely by foreign residents and/or temporary present residents on Census Day” has doubled during that time the Vancouver Sun reported. In 1986, it was 4%. By 2016, it had doubled to 8.2%.

“Exact definitions and measures have changed slightly over 30 years and patterns should be interpreted as directional,” Yan writes in a report released Wednesday.
